How to prepare:
Preheat grill to high heat.
Drizzle sliced fennel with olive oil, season with salt and pepper and grill on each side until grill marks develop, about 5 minutes each side.
Prepare the oranges by cutting the segments out in between the membranes. Combine the segments (with their juice), the olives and the parsley. Add the grilled fennel and toss.
In a small bowl, whisk all dressing ingredients together and pour over fennel salad.
Serve garnished with parmesan shavings.
